LT3472EDD#PBF概述

LINEAR TECHNOLOGY  LT3472EDD#PBF  芯片, 升压稳压器, 双路, 2.2-16V, 1.1MHZ, 10DFN

The is a 2-channel Switching Regulator generates positive and negative outputs for biasing CCD imagers. The device delivers up to -8V at 50mA and 15V at 20mA from a lithium-ion cell, providing bias for many popular CCD imagers. Switching at 1.1MHz, the LT3472 uses tiny, low profile capacitors and inductors and generates low noise outputs that are easy to filter. Schottky diodes are internal and the output voltages are set with one resistor per channel, reducing external component count. The entire solution is less than 1mm profile and occupies just 50mm2. Internal sequencing circuitry disables the negative channel until the positive channel has reached 88% of its final value, ensuring that the sum of the two outputs is always positive. Separate soft-start capacitors for each output allow the ramp of each output to be independently controlled.
